Finally got all the DB readings.
Since the OP was having issues with passing Laguna Seca's DB limits I measured using the track distance listed on their website.
All taken at 50ft distance perpendicular to the side of the car.

Stock BDR exhaust: Idle 82DB, WOT 4500 102DB
Flowmaster 30" slimlines Idle 72.5DB, WOT 4500 97.9db
